How it works.
• I had the participant’s hold their breath as long as possible.
• Since the height and weight could effect lung capacity I had them write them down.
• I also had them write down what sports they have played during the school year, since their physical activities could effect their breathing. Hypothesis
I predict….that larger people will have more lung capacity since they would have more room.
Variables
Independent variable-height and weight
Dependant Variable-Time they held their breath in minutes and seconds
Controlled Variable-equal number of girls and boys
Procedure
Have the participants hold their breath for as long as possible.
Time it.
Write down what sports they play.
Write down their height and weight.
Conclusion
• The result was very surprising to me. There was no significant pattern.
Possible causes of error
Some people might not have held their breath fairly.
Possible applications
Trying to hire a singer? Now you know that it doesn’t matter what gender you choose.
Further research
I could have timed people myself instead of having them do it themselves.
Acknowledgements
I would like to thank Mrs. Riffel for giving me so many ideas. I would also like to thank my mother who helped me in decorating my board and encouraging me and all the people that I tested for being so patient with me.

Problem
How does height, weight and gender affect lung capacity?
Introduction
I have a goal to get as much lung capacity as possible so that my singing could improve. Seeing how height and weight effects it could help me out.
